CPS:Process chain restart skipping step in error

Hi all,

This is to ask for input on how to handle BW process chain restart, skipping failed steps. Business case would be for instance as follows :

A process chain has 4 steps.

When submitted step 1 ends OK, step 2 fails. The process chain ends up in status Console and steps 3 & 4 are in status Skipped.

Objective is then to restart the chain from step 3 (i.e. step 2 in error would be skipped)

A first attempt was done by restarting the chain in BW directly but then the processing is not reflected in CPS. I’d assume this is expected behavior but I’m not sure. Is that correct ?

Then I tried to submit the process chain with parameter “Make Process Restartable If Errors Occur” = All.

When the process chains ends in “Console” status, replying to the “Restart process chain?” message allows me to select the jobid of any step. When selecting the one of the step 3, then the process chain ends in status “error”, the step 3 is not restarted (still skipped) and following error is produced at step 3 level:

Operator Message An error has occurred in the SAP connector: Exception while calling RSPC_API_PROCESS_RESTART: 126: ONLY_UNCHECKED


RSPC_API_PROCESS_RESTART is actually a SAP function module and ONLY_UNCHECKED is an "Exception" related to it. But error msg is not telling a lot.

Any idea what the issue could be and how to sort it out ?

Thanks in advance

Regis

    Hi Regis,

    What was the value of the parameter "Make processes restartable on error?" (CHAIN_RESTARTABLE) ?

    Also, in CPS, for the definition of the process chain, what was the value of BW_RESTART_UNCHECKED, this should be set to Y if you think you know what you are doing.

    Basically, in BW, a process chain is restartable or not, CPS by default honors this, if you set BW_RESTART_UNCHECKED to y, you "allow" CPS to "force-restart" the process chain without checking restartability. Note that if the process chain is set to not-restartable in SAP (which appears to the case) there "might" be a reason, please check.

    Regards,

    HP

      Hi HP,

      My version is 33.85 so it might be the reason why this help file is not available on my system. In the meantime, I saw that you posted its content in a blog.

      Many thanks for your help on this topic, it answered my question and allowed me to learn a lot on process chains handling.

      Best regards,
